gives the design for a filter for multi-rate signal processing

dc motor of simulink and pid controller

sdes based encryption.it is a simplified version of des algorithm

带有遗忘因子的递推最小二乘估计法，可以用来辨识时变参数的程序(Recursive least squares estimation with forgetting factor can be used to identify time-varying parameters.)

A useful wrapper over the boost Mersenne Twister random number generator. It is implemented as a singleton such that the same instance can be used throughout a code by requesting the singleton instance. It also can return the host rng for boost functions that requires it. A unary function is also provided for use with std::random_shuffle for example.

蚁群算法是一种模拟进化算法，初步的研究表明该算法具有许多优良的性质。(Ant colony algorithm is a novel simulated evolutionary algorithm, the preliminary study shows that the algorithm has many good properties. )
